This is a design circuit for a simple Digital Ammeter Circuit Diagram using DMS-30PC-0-RS from Murata Power Solutions. This digital ammeter is basically a very sensitive voltmeter with a typical input range of ±200mV. The circuit below depicts that the voltage across the shunt is only 0.1Vdc above pin 3 (5V RETURN). This is the figure of the circuit;
This is well below the ±2V common mode voltage limitation of the meter. The 0.1Ohm shunt, with 1.0 Amperes through it, will develop 0.100Vdc or 100mV across it.
Hi,
ReplyDeletePlease explain what type of LCD display should i use ?. And please tell me the reason for connecting load to 5v supply.( My load is working with 12v)
